The problem is it runs against modern culture to the point that you have a choice between privacy and participation in culture. If you want health care, you can't have privacy. If you want to buy things, you can't have privacy. If you want to use the internet, you can't have privacy. Even aggressive protection only somewhat buffers the intrusions.
Society reflects that. I remember being taught never to give out a phone number except to friends or businesses I wanted to talk on the phone with (e.g. a pizza restaurant). Now cashiers routinely demand phone number and zip code and other personal information with ever transaction, even if I'm paying cash. The fact that they're shocked and offended when I say no indicates that this is a very rare occurrence. Same when I refuse to sign something in an office or ask to see a privacy statement. Nobody's doing that either. There isn't time for everyone to do that even if they wanted to. It's a problem.
Mostly what I see is the same pattern from sexual abuse: either people have extremely tight boundaries, or don't even bother trying to set boundaries since nobody respects them anyway. The latter prevails, more and more as you go younger in ages. Then people wonder why teens send sex pictures to each other. Why wouldn't they? You've taught them that boundaries don't exist.
